TOOL FOR ATT-ACHINGI- HGSE TO COUPLINGS.

Specification of Letters Patent.

Patented Sept. 11, 1906'.-

Application filed May 21, 1906. eri'al No. 313.105.

To all whom it may concern.-

Be it known that I, ELMER A. WILoox, 'a citizen of the United States,residing in Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Tools for Attaching Hose toCouplings, &c., of which the following is a specification.

This invention relates to the construction of a tool to be used inattaching hose to couplings and pipes and is intended for use withfastenings made of wire.

The invention consists in the novel construction and combination ofparts hereinafter set forth, and illustrated in the accompanyingdrawings, in which Figure 1 is a plan of the invention, showing it atthe commencement of the operation of securing the hose. Fig. 2 is a sideview showing the hose and coupling in section. Fig. 3 shows the tool ata subsequent stage of its operation. Fig. '4 is a longitudinal sectionof the tool. Fig. 5 is an end view, and Fig. 6

. shows the hose and coupling after the completion of the attachment.

In said drawings, 7 represents the hose, and 8 a coupling to which thehose is being attached by means of a wire fastening 9. This wirefastening is bent in the customary manner into U form and placed aroundthe hose, with its ends 10 passed through the loop formed at thedoubledv end of the fastener. My improved tool is then brought into use.This tool consists of a cylinder 1 1, a tightener 12 for ti htening thewire fastener, such tightener eing threaded at its outer end, as at 13,and a winged nut 14 engaging the said threaded portion of the tightenerand locked in the cylinder in such manner as to permit it to turnwithout changing its position in the cylinder or becoming detachedtherefrom. This locking of the nut is desirably effected by recessingthe outside of the nut, as shown at 15, and sinking or compressing thatportion of the cylinder surrounding such recess 15 into the same, asplainly shown at 16 in' around one or both of which the ends 10 of thewire may be wrapped in the manner indicated at Fig. 1 in full lines orin the manner indicated at the same figure in broken lines, the lattergiving the greater resistance and enabling the tightening of thefastener to a lgreater degree than the method shown in full ines.

The tightener being positioned against the crotch of the wire is nowtightened by turning the nut, forcing the tightener to advance and drawupon the wire until it becomes tight around the hose, the resistancenecessary to permit this being obtained by the contact of the cross-headwith the hose. After the tightener has been forced out to the desiredextent the tool is reversed from the position of" Fig. 1 to that of Fig.3, turning upon the projecting point of the tightener in the operation.This bends the ends 10 around the crotch of the wire, so that they holdthe tension then existing upon the fastener. The tool is now releasedfrom the wire by retracting the tightener and may then be removed, theexcess wire in the points 10 being preferably cut off, and the fasteningwill then appear as in Fig. 6. The cross-head 18 is preferably recessedat each side, as plainly shown at 21 in Figs. 3 and 5, so as to ive roomto the wire and allow the flat or hearing portions of the cross-head tocome in contact with the hose.

A tool constructed according to my invention is not only very efi icientin operation, but it is also simple and durable.

I claim- 1. The tool for applying wire fasteners to hose, couplings,&c., consisting of a cylinder having a longitudinally-movable tightenertherein, an operating device on the end of said tightener having athreaded engagement therewith, and locked to the cylinder, and across-head on the cylinder rovided with pins for securing the ends of te fastener.

2. The tool for securing the wire fasteners of hose, cou lings, &c.,consisting of a hollow body, a tig tener movable longitudinally in saidbody and adapted to engage the crotch of the wire fastener, saidtightener being threaded at its outer end, an operating-nut threaded onsaid tightener and locked to said body and a cross-head on the operatingend of the body having pins at each side of the body adapted to securethe free ends of the wire fastening.

3. The tool for securing the wire fasteners of hose, cou lings, &c.,consisting of a hollow body, a tig tener movable longitudinally in saidbody and adapted to engage the crotch of the Wire fastener, saidtightener being threaded at its outer end, an operating-nut threaded onsaid tightener and locked to said body and a cross-head on the 0 eratingend of the body having pins at eac side of the body adapted to securethe free ends of the Wire fastening, said cross-head being also 10grooved to give room to the Wire fastening and allow the cross-head tocome in contact With the hose.
